Abstract
Description
Technical Field
[0001] This utility model relates to the field of wall waterproofing technology, specifically a detachable through-wall waterproofing device. Background Technology
[0002] In construction fields such as building and municipal engineering, it is necessary to pre-install embedded sleeves in basement retaining walls and rooms with waterproofing requirements to facilitate subsequent pipeline construction. Due to the influence of many factors such as deformation of the wall-penetrating pipe and the structural concrete, temperature stress changes, and different media, the area around the wall-penetrating pipe is very likely to become a point of waterproofing leakage.
[0003] Existing through-wall pipe structures typically employ waterproof membranes or coatings on the water-facing side and inside the building to ensure a tight seal and waterproof effect. However, due to construction operations and subsequent factors such as building vibration, settlement, and displacement, this area is highly susceptible to water seepage. Summary of the Invention

Detailed Implementation
[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0018] Example: Figures 1-2 As shown, a detachable through-wall waterproofing device includes a main pipe 1. A sleeve 2 is installed on the outer periphery of the main pipe 1 at the location on the wall 16. The inner diameter of the sleeve 2 is 35mm larger than the outer diameter of the main pipe 1. Small steel bars are used to support the sleeve 2 and the main pipe 1 to ensure that the circumferential seam between the sleeve 2 and the main pipe 1 is consistent and to prevent displacement of the sleeve 2. The space between the main pipe 1 and the sleeve 2 is filled tightly with a sealing material, and both ends of the sleeve 2 are sealed. The length of the filling material can be 3-5 times the diameter of the sleeve, but not less than 100mm.
[0019] Furthermore, the inner end of the sleeve 2 near the interior is provided with a double-layer first sealing tape layer, and the inner end of the sleeve 2 near the water-facing side is provided with a double-layer second sealing tape layer. Two rubber rings 10 are provided on the outer end of the first sealing tape layer, and a short pipe 13 is provided on the outer end of the rubber rings 10. A flange 12 is provided on the outer end of the short pipe 13, and the flange 12 is connected to the wall 16 via double-ended bolts 11 and a flange 14. A retaining ring 15 is provided on the inner end of the first sealing tape layer and is fixed to the inner wall of the sleeve 2. An asphalt-impregnated hemp fiber filling layer 4 is provided on the outer end of the second sealing tape layer, and a 20mm thick waterproof sealant caulking layer 5 is provided on the outer end of the asphalt-impregnated hemp fiber filling layer 4. A main pipe fixing ring 3 is provided on the inner end of the second sealing tape layer and is fixed to the outer wall of the main pipe 1.
[0020] Furthermore, the outer wall of the sleeve 2 is connected to the wall 16 via a wing ring 9. The wing ring 9 is made of 8mm thick steel plate with a wing height of 100mm. The wing ring 9 is located in the middle of the wall 16 and welded firmly to the surrounding structural reinforcement. Its axis is perpendicular to the wall surface, and the pipe cross-section is flat. A metal clamp 6 is installed on the outer wall of the end of the sleeve 2 closest to the water-facing side. The sleeve 2 is tightened by the metal clamp 6 and sealed with sealant. An additional waterproof layer 8 is also installed on the outer wall of the end of the sleeve 2 closest to the water-facing side. The additional waterproof layer 8 is located inside the metal clamp 6, and a building sealant sealing layer 7 is installed between the additional waterproof layer 8 and the sleeve 2.
